When it comes to saving for retirement, 401(k)s and individual retirement accounts (IRAs) are probably the most well-known types of retirement accounts. But just because they’re the most common doesn’t mean they’re your only options. There are many different types of retirement accounts, each with their own limitations and eligibility requirements and tax rules.

Whether you’re an employee or your own boss, here’s a look at nine types of retirement accounts that you can use to save for retirement.

Employer-sponsored retirement accounts

Retirement accounts made available through an employer are known as employer-sponsored accounts. These include:

1. 401(k)

What it is: A 401(k) is perhaps the most popular of all employer-sponsored retirement accounts because contributions are made automatically with each paycheck and employees may receive a partial or full match from their employers, allowing them to more quickly build their retirement nest egg. 

401(k)s come in two main varieties: traditional and Roth.

In a traditional 401(k), contributions are made with pre-tax money, lowering the employee’s taxable income for the year contributions are made. When withdrawals are made in retirement, those withdrawals are taxed.

In a Roth 401(k), contributions are made with after-tax money. This means there are no tax savings when contributions are made but withdrawals will generally be tax-free in retirement.

Who it’s for: Eligible employees of private, for-profit companies.

2022 contribution limits: Up to $20,500 per year for those younger than 50 or $27,000 per year for those 50 and older.

2. 403(b) plan

What it is: A 403(b) is a retirement account offered by public schools, certain charities other nonprofit organizations to their employees. They used to be called tax-sheltered annuities (TSAs) and are like 401(k)s, in that:

• 403(b)s can be either traditional or Roth
• Employers may choose to provide a partial or full match to employees’ 403(b)s
• 403(b)s have the same contribution limits as 401(k)s

Who it’s for: Eligible employees of public schools, government and other non-profit organizations.

2022 contribution limits: Up to $20,500 per year for those younger than 50 or $27,000 per year for those 50 and older.

3. 457(b) plan

What it is: A 457(b) is a retirement account available to eligible employees of state and local governments, including civil servants, police officers, firefighters and others. The 457(b) has many similarities to 401(k)s, including:

• Both come in either traditional or Roth varieties
• Both share the same contribution limits
• Both offer a potential employer match
   

There are, however, certain differences you should be aware of.

If you need to make a withdrawal from your 401(k) or 403(b) before you are of retirement age (59½), you will be subject to a 10 percent early withdrawal fee. This fee does not impact savers with a 457(b) account.

In addition, 457(b) accounts usually have the same contribution limits as a 401(k) or 403(b) account.

Who it’s for: Eligible state and local government employees.

2022 contribution limits: Up to $20,500 per year for those younger than 50 or $27,000 per year for those 50 and older. Those in their final three working years before retirement can contribute more depending on their contribution history, up to a maximum of $41,000 per year.

4. SIMPLE 401(k)

What it is: A SIMPLE 401(k) is a special type of account for businesses with fewer than 100 employees. They are like regular 401(k)s, with a few key differences:

• Employers offering a SIMPLE 401(k) are required to provide a contribution. This may be either a dollar-for-dollar match (up to 3 percent of the employee’s annual pay) or a nonelective contribution of 2 percent of the employee’s annual pay.
• Employer contributions to a SIMPLE 401(k) are vested automatically (meaning they’re available if the employee leaves the company), while employer contributions to regular 401(k)s typically vest over time.
• The contribution limit for a SIMPLE 401(k) is lower than for a regular 401(k).
   

Who it’s for: Eligible employees working at companies with fewer than 100 workers.

2022 contribution limits: Up to $14,000 per year for those younger than 50 and up to $17,000 per year for those 50 or older.

5. SIMPLE IRA

What it is: Like the SIMPLE 401(k), the SIMPLE IRA is a retirement account for businesses with fewer than 100 workers. SIMPLE IRAs have other similarities with SIMPLE 401(k)s, including:

• Employers are required to provide an employer contribution. This can either be a dollar-for-dollar match (up to 3 percent of the employee’s annual pay) or a nonelective contribution of 2 percent of the employee’s annual pay. That said, with a SIMPLE IRA, employers have more flexibility around contributions compared to a SIMPLE 401(k).
• Employer contributions to a SIMPLE IRA vest immediately instead of over time.
• The contribution limits for a SIMPLE IRA are $14,000 per year for employees younger than 50 and $17,000 for those 50 and older.

Unlike a SIMPLE 401(k), there is no Roth version of a SIMPLE IRA. Additionally, while a SIMPLE 401(k) may allow for loans, you cannot borrow from your SIMPLE IRA. If an employee participates in any other employer plan during the year and has elective salary reductions under those plans, the total amount of the salary reduction contributions that an employee can make to all the plans he or she participates in is limited to $20,500 in 2022. 

Who it’s for: Eligible employees working at companies with fewer than 100 workers, as well as individuals who are self-employed or sole proprietors.

2022 contribution limits: Up to $14,000 per year for those younger than 50 and up to $17,000 per year for those 50 or older.

Personal retirement accounts

Besides the employer-sponsored accounts listed above, you can also open a personal retirement account on your own. Some of these can be opened in addition to an employer-sponsored plan, while others are intended to replace employer-sponsored plans (for example, in the case of those who are self-employed).

1. Individual retirement account (IRA)

What it is: An IRA is an individual retirement account that does not need to be sponsored by an employer.

Like 401(k)s, IRAs are tax-advantaged and can come in either traditional or Roth varieties. Differences between IRAs and 401(k)s include:

• IRAs tend to offer more investment options compared to 401(k)s, allowing you more control over how you save for retirement.
• IRAs have much lower contribution limits: $6,000 per year for individuals younger than 50 or $7,000 per year for those 50 and older.
• To make the full contribution to a Roth IRA, you must fall under a certain income limit: $129,000 for single filers and $204,000 for those who are married filing jointly. Eligibility phases out to zero once your income hits $144,000 or $214,000, respectively.

Who it’s for: Anyone who has earned income during the year can contribute to an IRA.

2022 contribution limits: Up to $6,000 per year for those younger than 50 and $7,000 per year for those 50 or older.

2. SEP IRA

What it is: A simplified employee pension, or SEP IRA, is a type of retirement account primarily for individuals who are self-employed (and for some employees of small businesses).

SEP IRAs are often described as a mix between an IRA and a 401(k). This is primarily because a SEP IRA has a much higher contribution limit compared to a regular IRA. And though you cannot open a Roth SEP IRA, you can roll your SEP IRA over into a Roth IRA.

Who it’s for: Self-employed individuals, small-business owners and some employees of small businesses.

2022 contribution limits: Either $61,000 or 25 percent of the individual’s compensation for the year (whichever is lower).

3. Solo 401(k)

What it is: A solo 401(k) is a plan for a single, self-employed person. It may also be known as an individual 401(k), solo(k), uni-(k) or one-participant(k).

It shares many of the characteristics of a regular 401(k), but with some important differences. You can make contributions as both the employee and employer. These contribution limits are divided into two buckets:

• As the employee, you are eligible to contribute the same amount as individuals enrolled in other 401(k) plans. This means that individuals younger than 50 can contribute up to $20,500 per year to the plan, and those 50 or older can contribute up to $27,000 per year.
• As the employer, you are eligible to make an additional contribution of up to 25 percent of your compensation for the year (up to the total limits mentioned above).
   

Who it’s for: Self-employed individuals and solo entrepreneurs.

2022 total contribution limits: Up to $61,000 per year for those younger than 50 and $67,500 for those 50 and older, depending on your compensation for the year.

4. Spousal IRA

What it is: Opening a spousal IRA allows a working spouse to contribute to an IRA for the non-working spouse. Spousal IRAs are governed by the same rules as regular IRAs and can be either traditional or Roth.

Who it’s for: Non-working spouses who have not earned income for the year.

2022 contribution limits: Up to $6,000 per year for those younger than 50 and $7,000 per year for those 50 or older.

All contribution limits are as of 2022 and are subject to change.
